Microsoft confirms Windows 11 KB5083769 issues, BitLocker alert on a few PCs, and multiple reboots for installation

Microsoft has acknowledged issues with Windows 11 KB5083769 update, including triggering BitLocker recovery screen alerts on some PCs and requiring multiple reboots for installation. The update, released in April 2026, may cause errors like 0x800736b3 and 0x800f0991 during installation. Microsoft is investigating reports of the multiple reboots required for installation, possibly due to a .NET Framework update that was rolled out simultaneously. A server-side fix has been implemented to address the BitLocker recovery screen issue caused by an unrecommended BitLocker Group Policy configuration on certain devices.
